Bert W. Geary is a research technician at Borderlands Research Institute, working on the Trans-Pecos Mountain Lion Project. Before moving out to Far West Texas, he worked as a research associate in a fisheries ecology laboratory at Texas A&M University at Galveston. There he worked on several projects examining the factors that affect the distribution, growth, and recruitment of coastal and offshore marine fishes. Bert received his MS from Texas A&M University in Wildlife and Fisheries Sciences where his thesis focused on recruitment and the factors affecting recruitment in juvenile sciaenid fishes within salt marsh systems. Prior to that, Bert graduated with a BS in Marine Biology from Texas A&M University at Galveston. His current interests include island biogeography and how dispersal and recruitment affect populations within the sky islands of the Chihuahuan Desert, specifically large carnivore populations.
